Description

Technical Field

[0001] This utility model belongs to the field of color steel plate technology, specifically, it relates to a color steel sandwich panel. Background Technology

[0002] Color-coated steel sandwich panels are a new type of building envelope material that integrates load-bearing, thermal insulation, waterproofing, and decoration. They can be widely used in various construction needs, including industrial plants, public buildings, prefabricated houses, and cleanroom projects. These panels use color-coated steel sheets as the face material and self-extinguishing polystyrene, polyurethane, glass wool, rock wool, etc., as the core material. They are manufactured using thermosetting adhesives in a continuous forming machine through processes such as pressure, heat curing, edge trimming, grooving, and blanking. The thickness is generally 25-250mm.

[0003] Color-coated steel sandwich panels are characterized by their light weight, high strength, thermal insulation, fast construction speed, and vibrant colors (no surface decoration required, and the anti-corrosion coating of the galvanized steel sheet lasts for 15-20 years). Besides their applications in buildings and ship interior partitions, cold storage facilities, and highway sound barriers, color-coated steel sandwich panels are also widely used in other fields.

[0004] Existing color steel sandwich panels typically have U-shaped grooves on corresponding end faces. During assembly, adjacent U-shaped grooves of two connecting color steel panels are interlocked. However, this connection method can create a "cold bridge" phenomenon due to uneven heating, and it also easily leads to corrosion and damage to the end faces of the color steel panels. Therefore, it is necessary to improve this method. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] One embodiment of this application provides a color steel sandwich panel, such as... Figures 1-3 As shown, it includes: a first color steel plate 1, an inner core plate 2, and a second color steel plate 3. The first color steel plate 1 is disposed on the upper surface of the inner core plate 2, and the second color steel plate 3 is disposed on the lower surface of the inner core plate 2. It should be noted that the structure of the inner core plate 2 is prior art, and will not be described in detail here.

[0027] One end of the second color steel plate 3 extends to form a first recess 31, and the inner core plate 2 is provided with a first clearance part 21 for the first recess 31 to make way;

[0028] The other end of the second color steel plate 3 extends to form a first protrusion 32, and the inner core plate 2 is provided with a second clearance part 22 for the first protrusion 32 to make way; when two adjacent color steel sandwich panels are spliced ​​together, the first protrusion 32 of the first color steel sandwich panel and the first recess 31 of the second color steel sandwich panel cooperate, and after cooperation, the sides of the inner core plates of the two adjacent color steel sandwich panels are connected.

[0029] One end of the first color steel plate 1 has a first snap-fit ​​portion 11, and the other end of the first color steel plate 1 has a second snap-fit ​​portion 12. When two adjacent color steel sandwich panels are spliced ​​together, the second snap-fit ​​portion 12 of the first color steel sandwich panel cooperates with the first snap-fit ​​portion 11 of the second color steel sandwich panel. After cooperation, the sides of the inner core panels of the two adjacent color steel sandwich panels are connected. Then, the two adjacent color steel sandwich panels are fixed with fasteners 4, which has high stability. The fasteners 4 pass through the corresponding inner core panels 2, so that the fasteners 4 have a supporting function and the connection is reliable.

[0030] After the first snap-fit ​​part 11 and the corresponding second snap-fit ​​part 12 are engaged, an installation space 13 is formed between the first snap-fit ​​part 11 and the corresponding second snap-fit ​​part 12 to facilitate the installation of the fastener 4.

[0031] Furthermore, such as Figure 3 As shown, it also includes a buckle 5, which is fastened between the first snap-fit ​​part 11 and the corresponding second snap-fit ​​part 12. The buckle 5 covers the installation space 13 to prevent the fastener 4 from rusting, and at the same time, it also prevents rainwater from entering the splice of two adjacent color steel sandwich panels.

[0032] Furthermore, such as Figure 1 As shown, a plurality of flow-guiding protrusions 14 are provided at intervals on the first color steel plate 1. The flow-guiding protrusions 14 can enhance the bending resistance of the first color steel plate 1, and at the same time, they also play a role in guiding water.

[0033] Furthermore, such as Figures 1-3 As shown, the first snap-fit ​​part 11 includes a first snap-fit ​​body 111, the cross-sectional shape of the first snap-fit ​​body 111 is R-shaped, and the outer end of the first snap-fit ​​body 111 extends to form a first connecting plate 112.

[0034] The second snap-fit ​​part 12 includes a second snap-fit ​​body 121. The cross-sectional shape of the second snap-fit ​​body 121 is inverted R-shape. The outer end of the second snap-fit ​​body 121 extends to form a second connecting plate 122. The second connecting plate 122 is inverted L-shape and is attached to the side of the inner core plate 2. When two adjacent color steel sandwich panels are spliced ​​together, the second connecting plate 122 of the first color steel sandwich panel, which is inverted L-shaped, cooperates with the first connecting plate 112 of the inner core plate 2 and the second color steel sandwich panel. An installation space 13 is formed between the first snap-fit ​​body 111 and the second snap-fit ​​body 121. The buckle 5 is fastened between the first snap-fit ​​body 111 and the second snap-fit ​​body 121.

[0035] In summary, the beneficial effects of the color steel sandwich panel of this application are as follows: the connection between two adjacent color steel sandwich panels is seamless, and there will be no cold bridge phenomenon; the fasteners cooperate with the inner core panel to support the fasteners, and the connection of the fasteners is reliable; the buckle cap makes the connection between two adjacent color steel sandwich panels waterproof and prevents water seepage at the connection; the design of the guide strip increases the bending resistance of the color steel sandwich panel.

[0036] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
